The ODH harness gains namespace, release, command, readiness, and sandbox selector helpers. The test checks session reconnection, workload continuity, and cleanup.

Suggested reviewers: Merge Risk: ⚪ Minimal · up to This adds an opt-in failover end-to-end test and shared test helpers. It does not change production behavior. The test has not been run against a live OpenShift cluster, which is normal for this kind of change. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

- Around line 23-28: Separate namespace resolution by adding gateway_namespace()
and sandbox_namespace(): use NAMESPACE for gateway resources and
SANDBOX_NAMESPACE for sandbox resources, retaining the existing defaults and
fallback behavior where appropriate. Update gateway_failover and
image_provenance to use the matching helper for gateway discovery,
port-forwards, Sandbox queries, and Pod queries.

Add downstream ODH Tier 3 coverage for OpenShift HA Gateway failover

Goal: Verify that when one gateway replica goes down, the surviving replica(s) pick up sandbox state from Postgres and clients reconnect without data loss.
